CASE STUDY CONSERVATIONISTS COLLABORATE TO SAVE GIANT PANDAS SMITHSONIAN NATIONAL ZOOLOGICAL PARK In July 2005, many Americans were delighted by new reports about the birth and early development of Tai Shan, a giant panda, at the National Zoo in Washington, DC. This was a momentous event brought about by years of collaborative effort from reproductive biologists and veterinarians from the U.S. and China. Tai Shan was the fourth cub born in the U.S. and the first from the National Zoo s resident pair of giant pandas, Mei Xiang and Tian Tian. Although much excitement accompanies every zoo birth of a giant panda, the ultimate survival of the species depends on having a self-sustaining population in China.

PROTECTING GIANT PANDAS Only four zoos in the U.S. have giant panda pairs: Atlanta, San Diego, Memphis, and the National Zoo. These pandas are on loan from China. Giant pandas have been one of the world s most endangered mammals and those kept in captivity, including in the U.S., serve as an insurance policy against extinction. They are managed cooperatively across zoos worldwide, in an effort to maintain the maximum genetic diversity possible for the captive population. Although much excitement accompanies every zoo birth of a giant panda, the ultimate survival of the species depends on having a self-sustaining population in China. Thus, the National Zoo puts a lot of effort and funding towards research in China and capacity building for panda reserves. Tai Shan s parents were both born at the China Research and Conservation Center for the Giant Panda at Wolong Nature Reserve in Sichuan Province. This is one of over 50 protected areas in China, some of which are linked by wildlife corridors designed to facilitate movement and interbreeding between the separated wild panda populations. Currently pandas are separated into a number of different populations which are dispersed across six mountain ranges. cover conversion, and mining have depleted the habitat they need. As bamboo forests are converted for other uses, it is critical to protect the remaining habitat and monitor the wild populations. TRAVELING WITH TECHNOLOGY TO CHINA When the National Zoo received Mei Xiang and Tian Tian from China in 2000, they became ambassadors for a much larger mission. Beyond the excitement and educational opportunities provided by their arrival, a primary objective for the National Zoo was to work to improve the giant panda s chances for long-term survival through research and capacity building. Soon after the arrival of the pandas, the National Zoo began to hold workshops with our Chinese colleagues to collaborate on research projects and to support their panda conservation efforts. Training with geospatial technology was identified early on as one of their top priorities they recognized that imagery would be critical for wildlife management and research analysis projects. A recent China national panda survey counts an estimated wild panda population of 1,864, an increase of some 17 percent from a survey conducted in 2004. Pandas rely almost entirely on bamboo for their nutrition and therefore have very specific habitat requirements. Through the years, climate change and human activities have severely reduced the amount of panda habitat remaining. Over a 30 year period, panda habitat decreased by almost 25 percent estimated to be 29,500 km2 (11,390 square miles) during the first national survey in 1974, but down to 23,000 km2 (8,800 square miles) in a 2004 survey. The remaining areas are made up of deciduous and coniferous forests, interspersed with dense patches of bamboo forests and covering high mountains (panda habitat ranges from 4,000 to 11,000 feet in elevation). Dr. Liu Xuehua and Jin Xuelin demonstrate GIS techniques for students. In many of these areas, the pandas are in close proximity to farmers who plant crops in the river valleys and the lower mountain slopes.

At the Zoo s Conservation GIS Laboratory, we began working with our Chinese colleagues to adapt our applied GIS training course, GIS and Remote Sensing for Wildlife Managers, for use in China. We were able to take the basics and create applications that were relevant for panda reserve staff. Modules were based on data that s specific to local panda research and all training materials have been translated into Chinese. The training was led by U.S. and Chinese instructors, and throughout the training courses, there was a bilingual instructor present to help with communication. The National Zoo staff traveled to China to present the course in panda reserves for staff working in the reserves and forestry departments, as well as researchers from science academies and universities. The course provides step-by-step instructions for using Global Positioning System (GPS) units to collect data on the ground, the ERDAS IMAGINE software suite to rectify, view, and mosaic imagery, and GIS software for analysis and data presentation. GEOSPATIAL TRAINING During the course, we made our case studies as realistic as possible, using examples from different reserves to give the students a good sense of what we do in assessing a protected area. Upon completion, students have a basic understanding of how to store and analyze spatial data, how to use satellite imagery and GIS to map and monitor remaining habitat, and how geospatial analysis can be used as a management tool to assess how changes to a reserve may impact wildlife. Collecting Bamboo Data For example, one module illustrated how panda survey data can be used to assess habitat selection. Prior to habitat analysis, the students learned how to extract areas of interest from a satellite image. After they extracted the data, they learned how to perform an unsupervised land cover classification using ERDAS IMAGINE. Once they had the basics of image classification, they moved to the next module for habitat analysis. 4 CONSERVATIONISTS COLLABORATE TO SAVE GIANT PANDAS Smithsonian National Zoological Park
These modules teach students important operations, as well as encourage them to think about the possibilities of using remote sensing and GIS in their own reserves. 5 CASE STUDY Subtitle CONSERVATIONISTS COLLABORATE TO SAVE GIANT PANDAS Smithsonian National Zoological Park 5

The habitat selection analysis was based on data collected during surveys of panda dung and recorded via GPS in Wanglang Nature Reserve, Sichuan Province. Other data layers included were habitat, elevation, roads, and streams. By combining databases using spatial joins, querying attributes, buffering features, and searching databases, the students identified what habitat characteristics were most important to pandas. Next, these characteristics were used to map suitable habitat. WORKING TOGETHER A side benefit of this training has been increased collaboration among the reserves to share data and findings. Staff members from most of the reserves have attended our training and are familiar with geospatial concepts and potential for their projects. Greater levels of cooperation and information exchange have brought a wider understanding of panda conservation and challenges in terms of habitat loss and infringement. Once the skills are achieved, it would only be a matter of introducing the new data layers and using the same analytical approach to understanding the data. The birth of Tai Shan is an achievement shared by both National Zoo and Chinese conservationists. Tai Shan has returned to China to live permanently. Due to the great success of captive breeding programs, China has now begun to release captive born pandas into the wild, where we hope they will enhance the sustainability of the wild populations. He may only be one small bear, but Tai Shan is a symbol for the future, illustrating how we can work together, using geospatial technologies as our communication medium to improve cooperation and understanding and help save the giant panda. Melissa Songer, Ph.D., is the manager of the Conservation GIS Lab for the Smithsonian National Zoological Park (the National Zoo) in Washington, DC. As geospatial technology becomes an ingrained part of research programs in China, it can be used to examine living conditions and challenges of other vulnerable species. Other species of concern that share giant panda habitat are takin, golden monkeys, and even red pandas. He may only be one small bear, but Tai Shan is a symbol for the future, illustrating how we can work together, using geospatial technologies as our communication medium to improve cooperation and understanding and help save the giant panda.
